Are pistol squats worth it?

Pistol squats are a great addition to anyone's workout, especially if you have issues with back squats, they can be a great substitute. For those that have no problems with barbell back squats, they are simply a great addition to a solid lower body routine, helping to even up any bilateral leg strength deficit.
